VectorLinux is one of those useful but lesser-known Linux distros. It's
been around since 1999 and I've used it since 2006, off and on, in the
role of a secondary OS. Now, with the disruptive changes
Ubuntu forces on its user base with each new release, I've found myself
increasingly attracted to Vector's stability and convenience. This
article introduces "VL" to those who may not be familiar with it.

Vector looks really good in the screenshot gallery. But one thing: can someone tell me what the OS is in this screenshot? I particularly like the sidebar dock and minimalist menu bar. Any help in finding these things?
